2.5.3. Device Configuration Pins for Optional Configuration Signals

All configuration schemes use the same dedicated pins for the standard control signals shown in the Agilex™ 5 Configuration Timing Diagram. Many other optional configuration signals do not have dedicated pin assignments.

Device Configuration Pins without Fixed Assignments

Note: Although the CONF_DONE and INIT_DONE configuration signals are not required, Intel recommends that you use these signals as an indicator to ensure that configuration is successful. The SDM drives the CONF_DONE signal high after successfully receiving full bitstream. The SDM drives the INIT_DONE signal high to indicate the device is fully in user mode. These signals are important when debugging configuration.

Note: Intel recommends that you assign the CONF_DONE and INIT_DONE pins to SDM I/O pins 0 or 16. These pins have weak internal pull-downs resistors. If you cannot use these pins, Intel® recommends that you include external 4.7-kΩ pull-down resistors to avoid false signaling.
